The adaptive or acquired immune response refers to special cells int he lymphatic system that can recognize foreign invaders based on the antigens that they had seen for. A foreign invader enters the body, and the innate immune system responds quickly, and then with time the adaptive immune system kicks in to ght and kill the invader.
